Perhaps one motor at each end of an axel. That would make three or
four pairs with less gears.
Something like this:

[extremle quick and dirty pic to show what I mean]
Be sure to connect all the wires correctly so that they actually work
with each other and not against ,)
Connecting something to one of the gears in the picture above would
get a lot of power. I think.

I found during my Hercules building that three oldstyle 9V motors was
all that my powerbox could handle. With four motors it shut down.
Probably due to the thermal switch in the powerbox.
To overcome the danger of switching some powerbox on in the wrong
direction just use a polarity switch :)
